This part of ISO 17225 supports the use of graded non-woody pellets for residential, small commercial and public buildings as well as industrial energy generation applications, which require classified pellet quality The residential, small commercial and public building applications require higher quality fuel for the following reasons: • Small-scale equipment does not usually have advanced controls and flue gas cleaning • Appliances are often located in residential and populated districts • Appliances are not generally managed by professional heating engineers Non-woody pellets have high ash, chlorine, nitrogen and sulfur content and major element contents, so non-woody pellets are recommended to be used in appliances, which are specially designed or adjusted for this kind of pellet NOTE Pellets produced according to this part of ISO 17225 may be used in pellet burners tested according to EN 15270[1] and pellet boilers or integrated-pellet burner systems tested according to EN 303–5[2] NOTE When using non-woody materials for combustion special attention should be paid to the risk of corrosion in small and medium scale boilers and flue gas systems Be aware that herbaceous or fruit biomass may influence the fuel ash composition differently depending on growth and soil conditions The content of chlorine, phosphate and potassium in the material may form chlorides and phosphates and other chemical compounds resulting in high hydrochloric emissions and chemically active ash with low melting temperature causing corrosion NOTE In general non-woody biomass materials have higher content of ash forming elements and produces ashes with lower melting temperature compared to most woody biomass This may result in fouling, slagging and corrosion inside boilers These problems are especially related to materials that contain high content of potassium (K) and silicate (Si) and low content of calcium (Ca) NOTE For individual contracts ISO 17225-1 can be used Although these product standards may be obtained separately, they require a general understanding of the standards based on and supporting ISO 17225-1 It is recommended to obtain and use ISO 17225-1 in conjunction with these standards © ISO 2014 – All rights reserved Copyright International Organization for Standardization Provided by IHS under license with ISO No reproduction or networking permitted without license from IHS Licensee=University of Alberta/5966844001, User=sharabiani, shahramfs Not for Resale, 05/10/2014 00:50:12 MDT v `,``,`,,`,`,,``,`,,`,``,`,`,`,-`-`,,`,,`,`,,` -
